question 1: if an atom has z = 16, what is the nuclear charge of this atom? a. -16 b. -12 c. +12 d. +16 e. -10

question 1: if an atom has z = 16, what is the nuclear charge of this atom? a. -16 b. -12 c. +12 d. +16 e. -10
Answer
Explanation:
Step1: Recall atomic number meaning
The atomic number (Z) represents the number of protons in the nucleus of an atom.
Step2: Determine nuclear charge
Protons have a charge of (+ 1). So if an atom has (Z = 16) protons, the nuclear charge is (+1\times16= + 16).
Answer:
D. +16
